The provisi0n Of the beveled spring bolb CZ a(1 notched spline 0 insul'es quick engagement of the teeth of the tw0 0lutch )3rts as considerab16 force ]]11St be exerted in ordef t0 free the b01t from engagement with the rear n0tch, Ien06 the Slide When it begins t0 n]0ve, is quickly thrust int0 engagement with the hea(1 F', the engagement of the bolb with the inner recess of the spline Serv ing t0 prevent accidenta1 release 0f the cluteh parts.

In S01Ile cases, the Sleeve aand hlib G may each have tw0 lugs as Shown for instanee at an( in Eig. 6 s0 as t0 distribute the Strain upon the Sleeve and hub.

I do n0t ela.im broadly the 00mbination of a positive elutch With 10st In0tion connection between the Same nd the puney and a Spring through which power is applied t0 the pulley while this 10St motion is being taken up, as this con]bination has before been pro- )0Se(1 I10l' do I limt 1Tly invention in it;s broadest embodiment t0 a clutch pulley, aus it Will be evident that sa id inventi0n can be ap- )ied to a connecting and disconnecting Shaf Coupling by Sinlply D1aking the hub G a 00tltinuti0n of the collar J, the latter being seeured t0 0ne Shaft and the clutch Slide D being earried by the 0ther shaft. Such a con- Struction is illustrated in Fig 7, Which Shows G0llr J extendingforvvardly over the Sleeve nd provided With a lug 9 f0 engaging with 2 lug On the head E of Said sleeve, the collar being lllade intvo parts clal11ped t0- gether in the same manner 3S the G0llr J and hving two internal recesses, one for the reception Of the nut 77z, and the 0ther f0r the reception of the Spring I. The tw0 Seeti0ns of the shaft are represented t and L the cluteh Sleeve D being Splined t0 the shaft ^L' nd the collar J being secured t0 the Shaft Wih a clutch slide having a t00thed face, 3

fixed 001lar, a100se sleeve having a t00thed clut(...11ing'hed f0' engaging vvith the 0lutch slide, a hub on Sai(1 sleeve, aa 00iled Spring 00nnecting the Sleeve and hub nd lug8 f0rn1ed upon the Sleeve and hub but providing a Space through Which either nay trvel before engaging vvith the 0ther,such )I'vel eectiDg a tightening of the spring eonne0- tion between the Sleeve and hnb substantially as specmed 2. The combination of a Shaft or Shafts Glut011 Slide having a t00thed face, a' 100Se Sleeve having clutch head With t00thed face f0I' engging with the clutch Slide a hub lnounted on said Sleeve, a 00iled spring connecting the sleeve tl(l hub, lng8 f0I'II16(1 upon the Sleeve and hub and pr0viding a Space throu h which either ma travel before engaging with the 0ther, Such travel eecting a tightening of tbe spring, a Dut secured to the end of the sleeve, and a fixed e0llar engaging Said nut and retaining the hub 10n itudina1l in 1)0Sition on the Sleeve, substantiany as Speeied In testin10ny where0f have signed my nallle to this specification in the presen06 0f tw0 Subscribing witnesses.
